  • Patent number: 10397592
    Abstract: A method and an apparatus for performing multi-threaded video decoding are disclosed. The method takes use of a multi-threaded scheme to process an encoded picture stream on a picture by picture basis. In the method, multiple threads are used for performing video decoding at the same time, such as one thread for the operation of parsing input bits into syntax elements of one picture implemented by the first thread, another thread for the operation of decoding the parsed syntax elements of another picture into pixel values implemented by the second thread, and the other threads for the operations of the non-reference picture, such as bidirectional predictive picture, including parsing input bits into syntax elements and the subsequent operation of decoding the parsed syntax elements into pixel values. Therefore, the decoding speed is substantially increased, and the decoding efficiency is enhanced.

    Abstract: An integrated circuit (IC) comprising an enhanced passivation scheme for pad openings and trenches is provided. In some embodiments, an interlayer dielectric (ILD) layer covers a substrate and at least partially defines a trench. The trench extends through the ILD layer from a top of the ILD layer to the substrate. A conductive pad overlies the ILD layer. A first passivation layer overlies the ILD layer and the conductive pad, and further defines a pad opening overlying the conductive pad. A second passivation layer overlies the ILD layer, the conductive pad, and the first passivation layer, and further lines sidewalls of the first passivation layer in the pad opening and sidewalls of the ILD layer in the trench. Further, the second passivation layer has a low permeability for moisture or vapor relative to the ILD layer.

  • Patent number: 10294037
    Abstract: A carrier monitoring system and a method thereof are disclosed. The carrier monitoring system includes carriers for carrying and positioning at least one circuit board, and a reflow oven including a conveyor, a processing module and a database. When one of the carriers is placed on the conveyor, some sensing units are pressed by a plurality of bumps disposed on a bottom of the carrier, and each of the pressed sensing units transmits a sensing signal to the processing module. According to the sensing signals, the processing module obtains a carrier code; and, according to a plurality of identification codes stored in the database and the carrier code, the processing module can determine which carrier is placed on the conveyor. As a result, the technical effect of monitoring the carrier entering the reflow oven can be achieved.
